Provides a more upright, comfortable riding position by raising and retracting the original 7/8" (22mm) diameter tubular handlebar. No need to replace your handlebars - simply remove the original top clamp, place the riser between the handlebar and original bottom clamp, and install the replacement top clamp using included hardware. Barbacks increase handlebar height by 31mm and move them back 22mm, producing an overall handlebar displacement of 35.4mm (1.4") at a 45 degree angle from the original position.
